Thank you Tom, I appreciate it.

Looks like impeller 1 needs finished   

Berkley or Dominator Jet Impeller/A Cut Alum/Ware Ring Item number: 280312167327

This is the info for the auction on ebay.

Tom, what are you telling us?  What brand is impeller 2??

I can't remember how far down we moved the plate.  It was lowered to help pull 5 skiers at the same time.  It pulled 3 on one ski and two double.

We just wanted to see if old blue could do it.  You should have seen the hole it blew in the lake!   Yes they all got up.  We nearly sank the chase boat making a turn by his bow    the wave came in the front of their bow rider.

It had the stock engine with a torker intake, comp cams 280 cam and a holley 750.   I never worried about top end back then because it really didn't have much to worry about.   52 MPH with the normal load of 50 gallons of fuel 4 people and gear.

I built the new engine last winter and would just like to see 65 MPH. (GPS)   It's just me and my wife most of the time now days and I'd like to see what she'll do.   If it does 65 with a new impeller and is more dependable that's great.  If it's stuck at 62 I can live with that just fine also.

I don't open it up that much but when the lake lice try to do the buzz and go by I like to show them the jet from time to time.   

I wonder what she'll do unloaded.....  1/2 tank of fuel, no cooler put the wife on the bank....  hmmmm

I came across an ebay auction for impellers.  The guy said they were CP made for berkeley.

Any ideas of the quality?

So then in your opinion what should I try in order to possibly pick up a couple MPH but not rev it over 5500 rpms?

I think I'm still thinking backwards on the AA A B deal.

AA less rpms  but takes more engine to turn it.

B  more rpms with less engine to turn it?

No loader.  What type would be the way to go?  I know nothing about them either 

 

So, I don't want the AA as I don't need more dig.  I'm looking for 65 mph from 61 to 62 I have now.

 The reason I was adding the impeller in the quest for that MPH was it's from 1977 and has some nicks.   I want to make sure it's up to the added HP without popping it's cookies due to metal fatigue.

I think we're narrowing this down.  I believe you're saying stay with an A or go to the B.....

The only weak link in the engine is the long bolt logs.  Everything else is set up to breath quite well.   The logs are port matched which is about all I can do with them.

Am I getting warm?  A or B

My cam tops out around 5900 max.    It's best torque and HP numbers are in the 5500 range.

It's a Comp cams marine 278.

Oh well, I have a couple months to figure it out     The lake is FROZEN

$50.00   

It's nice to see I'm not alone!  Nice boat!

Carlsons  were built in California till at least 1978, then moved to Texas.   I really like the CV23 and just couldn't believe I was the only one. 

No they aren't the fastest boats on the lake but move very well for a boat with a cuddy.

Thank you Romper for your info.   I think I'll  stick on a 100 shot and see how she likes it.  If it does work well should I pick up a heating pad too?

Thanks again
